Shaft H7 is fornird in sui-.- tionshavingr intnrfittiug ends, as at til. 'lho hvaring and parking hox 8Harc securod to the crank case by bolts extending through flanges on thebearing and the crank ease and-through one of the side walls 21 of the,hood. The crankshaft. is formed in sections to permit the bearing SS andthat section of the shaft t0 which the gear 8G is Secured to be securedin position and removed from the outside of the easing.

In assembling the apparatusj bearingy 88 is scoured in position al'terthe hood has been placed over the eoinpreessor and after the jacket hasbeen placed around the oas- ,ing. lf at any time it should `he necessaryto repair the compressor, the bearing 88 can he removed from the outsideand with it the outer section of shaft S7 and gear 86 to make itpossible to lift the hood and jacket 30 oti' the body 14.

In assembling the machine, motor 18 is placed in position in chamber11T, so that its end portion lo will extend through jacke-t 3l), afterthe latterhas been placed in position. lf rena-ral of the jacket isdesired. the motor uan be drawn forwardly in chamber l? to iermit thexiacket to be lifted away from bodyv 1l. An oil reservoir ll-l isdisposed in chamber .40 and a pipe Sh) conducts lubricant from thereservoir to the bearingrh for the crank-shaft.

The apparatus ia designed vto he automatic in its operation. to compresathe ,spent re,- frig'erant whenever the temperature in the refrigeratorrises ahoe a predetermined point and lo discontinue the operation of theniotor when the temperature falls. below a predeterniined point. Athermostat 5l, of anv suitable construction placed in an)v desired partof the refrigerator. controla the operation of electrically operatedstMwind-stop mechaniam for the inotor 18. The operation of the latter iseonl rolled by a switch 5:5 which controlsv a circuit (not shown) from aSuitable source of potential. The key 53 of this switch is turned by a.Shaft 5-l`which is driven by power derived from a small electric motor55 through a gear train 56. Switch 53 is adapted to alternag-,ely openand close the circuit for the motor` 1S by successive quarterrevolutions, so that when the shaft has heenoperated a quarter ot' arevolution toelose said switch and circuit, it will remain stationaryuntil `the shaft and switch are operated another quarter ot' arevolution, to open the circuit.

The thermostat hasthree electrical contacts which are connected to threeposts 57, 5S and 59 by conductors 60. 61 and GQ, respectively. Theconductor 61 is constantly connect-ed to'the thermostat-switch member51*l which is adapted to contact with the contact-terminal 51c ofconductor 60 when the temperature rises sulliciently to render theoperation of the compressor necessary, and with a contact terminal 51when the temperature falls, :aul'liciently in response lo the.

circulation of the refrigerant in the retrig erating eoil. The mechanismfor controlling the operation of motor 53 and shaft 5l coniprises aconductor disk 63 and projecting segments (il which are electricallyconnected together and mounted on a wheel (ST of in sulating material, astationary contact (S5 which engager ringr |33. a bruhrontiuft l'iadapted to ride on wheel il? and segments (il, and a contact H8 scouredto one yide ol wheel "i7 and electrically connected to ring 63.

Contact-i (3S) and 7l are connected topost 57 by a conductor 73,4 Con-- tacts 7U and T2 arc connected to poet.79 by a conductor 74. A battery 751 has ite,` poles connected hyconductor To", 75"" to poets To and 7T. reipcotively. Contacts H5 andfill are insulated from eaeh other b v a block ti'r. 'The Small motor 55for driving the Shaft Il is incliuled in a conductor To which isconnected to poat 7T and contact (S5 and post 538. A conductor 79connecte post 5b' and post Tt and a conductor 90 connect` post 7G andthe contacte` Go.

Shaft Irl extends through one ,aide of liodiv il and a sleeve 10U whicheitenih` through jacket lill and iaconneeted to turn the pliig ofwater-valve lll. so that when the coin# pressor is being operated byluotor '13, valve lli will be open to cause coolingF water to iowthrough water-jacket 48 and chamber 20 and so that when the motor isinoperativeaaid valve will he closed. The plugr ot' the latter ia formedwith a through port so that the valve will he alternatelv opened andclosed by suieeaive quarter revolutions of shaft 5l'.

The operation of the controlling nu elianisin will he as follows:Assuming: the apparatus to be at rest and the temperature in therefrigerator rises to a point when the apparatus should be operated locompresa the spent refrigerant, a circuit t'o'r operating;r motor 5S torotate Shaft 5l and operate Switch 53 and valve 4G a quarter revolution,will he established as follows: batterv1 T5. conductor 75, post 7T,eomluctor 79 in which the. motor is' included` contact (lo. disk (i3,contact (lo, contact T0 or 72. conductor 74, post :'19, conductor iLcontact 5l, mene her 51a, conductor (il. post 5S, conductor 7%), post Toand conductor 75h.

The casing' is placed upon a bed 101 of cork or other suitableinsulating:` material to prevent heat transference between the casingand the support in the refrigerator upon which the apparatus isinstalled.

ln some instances. il is' desirable to provide a body ol' brine or othersuitable retaining agent` and when this is desired, al brine tank IUI.-adapted to lit` around the jacket Jill, as' shown in Figs. L), 25, t,l() and ll, is provided. This tank compris s inner and outer and bottomwalls and the refrigerating coil 2525 is dispos-eil in the tank so thatthe brine will be cooled h v the refrigerant. rlhis tank is removablel'rom the jacket with the refrigerant coil l contained therein. l thel'ronl ot' the casing. the hot tom ol' the brine tank is disposed abovethe ing,r therein will next be placed around the.

casing. The brine tank and refrigerating coil will then'be placed aroundthe jacket 30. The motor can readily be installed in chainber 1i' t'rouithe open front of body 14 after the insulating jacket has been placed inposition. The bearing 88 with the outer section ot' the shaft 87 willthen be secured in place. The shaft 54 for operatin the water valve. 4Ucan be extended throng i the body il and jacket 30 from the inside 0fchamber 17. The remaining pipe connec-V tionl for the refrigerating coiland supply ot' cooling water can he maderfrom the outside either afteror before the jacket has been placed in position. To install theapparatus in a refrigerator, the assembled apparatus is placed thereinand.it is only necessary to connect the water-supply and discharge-pipesto the base. of body 14 and` make, the necessary electrical connectionsfor the motor 18 and the thern'iostat to conlplate the installation. Inevent repairs are necessary to the compressor, the apparatus may bedismantled by disconnecting and removing the refrigerant coil and brinetank, moving the motor 18 in chamber 17 to withdraw its projecting end18 from the jacket 30,. removing bearing SS with the outer Shaft isection of the crank shaft of the compressor, and lifting ott' thejacket 30 and removing the insulation, which will give access to thehood 2l so that it can be removed.

The invention thus exemplities an improved ret'rigerating machine whichis particularly adapted to be installed as a substantially complete unitin the ice chamber ot an ordinariY refrigerator. The refrigera 'ing coilis looped and coiled around the casing containingr the ol'ieratingmechanism, so that theI apparatus as a whole will oecu y littlespaee ina refrigerator. The motor or operating the compressor is incased so thatit can be installed with the compressor, and provision is made forpreventing the heat, resulting from the operation of the motor, frombeing conducted to the chamber around the casing. Provision is made fora brine tank around the casing. The connections for the refrigerant alidwater lines extend through the body containing the mot( and serving as abase for the compressor and receiver, so that the necessity of extendingthese lines through the sidua of tlm casing or jackot is avoiiloii, Tiniapparatus can lio readily as senibled and disiiiaiitliwl iii viiiiti'upaii'h are necessary.
